OIL-CUP.

To all whom it may concern:

Be it known that we, EDWARD M. ADAMs and EDWARD A. SHUTT, citizens of the United States, residing at Akron, in the county of Summit and State of Ohio, have of devices for supplying oil to moving parts of machinery to be lubricated and is designed to provide a novel structure embodying regulating means for controlling the outflow of the oil from a reservoir or font so that the quantity of lubricant fed in a given time may correspond to the amount consumed by the machine with which the lubricator cooperates.

The invention consists of a barrel arranged within a fount or reservoir and having an opening in its lower end, a regulator snugly fitted within the barrel and consisting of a stem having a plurality of grooves or feed ducts in its sides varying in size according to the amount of oil to be discharged. in a given time, and indicating means to correctly determine the position of the regulator so that the required feeding groove or duct may be selected and properly positioned to register with the inlet opening in the aforementioned barrel.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accom anying drawings.

Whi e the invention may be adapted to difierent forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiment is shown in the accompanying drawings, in which: I

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The lubricator consists of a reservoir or font 1 for containing a quantity of oil and Specification of Letters Patent.

' may be of any capacity and shape according to the specific requirements. A barrel 2 is located within the reservoir 1 and is attached to the bottom thereof preferably by means of a screw joint which tends to admit of the barrel being removed for any purpose or readily placed in position and made secure. A11 inlet opening 3 is formed in a side of the barrel 2 near its lower end and a short distance above the bottom of the reservoir thereby leaving a space below the same for the accumulation of sediment or other impurities that the oil may contain. The barrel opens through the bottom of the reservoir and delivers the lubricant in regulablequantity to the part to be lubricated. A regulator 4 is snugly fitted within the barrel 2 and consists of a stem which is provided in its sides with a plurality of grooves or feed ducts 5 for the escape of the lubricant, said regulator being adapted to be turned to bring any one of the grooves or feed ducts 5 in position to register with the inlet opening 3. The grooves or feed ducts 5 vary in size each being slightly larger than the other in progressive rotation about the stem of the regulator.

To correctly position the grooves or feed ducts so as to register with the inlet opening 3 and to admit of any sized groove or duct being selected the following means have been devised: A series of notches 6 are pro vided in the upper end of the barrel 2 and a pin 7 projecting laterally from the upper end of the regulator or the stem 4 is adapted to 'enter one of the notches 6 so as to holdthe regulator in an adjusted position and insure registry of the selected groove or duct 5 with the discharge opening 3. The pin 7 also serves as a finger piece when manipulating the regulator and is rasped when it is desired to lift the regu ator and to turn the same either to the right or to the left as may be found most convenient to bring a selected groove in register with an inlet opening 3.

at the upper edges 0' the walls of the reservoir or font 1 and cooperate with the pin 7 to designate which of the grooves or feed ducts is in operative position or in register with an inlet opening 3. The notches or indicating marks 8 are different in character or varying in number so that the 'end of the groove in register with an inlet opening 3 may be designated. When the pin 7 is turned to point toward the single notch the Notches or indicatin marks 8 are provided smallest groove or feed duct is in'register with the opening 3 and when the said pin is set to turn toward the double notches 8 the next groove or feed duct in order registers with the inlet opening 3 and so on for the re-,

supply to prevent heating of the parts or the unnecessary wear thereof through lack of pro er supply of lubricant. The grooves or feet ducts may be cleared in an instant by removing the regulator or stem 4 and wiping the same so as to remove any obstructing matter or gum.

Having thus described the invention, what is claimed as new is: 1. In a lubricator, the combination of a reservoir, a barrel projecting within the reservoir and provided at one end with a discharge opening and in its side with an inlet opening, a stem fitting closely within the barrel and provided with a plurality of longitudinal feed ducts of various sizes, any one of the said feed ducts being designed to establish communication between the inlet and the discharge opening, and means for rotating the stem .to throw any selected one of the feed ducts into registry with the inlet.

2. In a lubricator, the combination of a reservoir, a barrel projecting within the reservoir and provided with a discharge openingand also in its side with an inlet opening, one end of the barrel having notches formed therein, a stem fitting closely within the barrel and provided with a plurality of longitudinal feed ducts of various sizes, and a pin carried by the stem and adapted to engage one of the before mentioned notches in the end of the barrel to hold any selected one of the feed ducts in cooperative relation to the inlet opening and the discharge opening.

3. In a lubricator, the combination of a reservoir, a barrel projecting within the reservoir and provided with a discharge opening and a feed opening, one end of the barrel having notches formed therein, a stem fitting closely within the barrel and provided with a plurality of feed ducts of various sizes, a pin 1 carried by the stem and adapted to enga e one of the before mentioned. notches to ho d any selected one of the feed ducts in cooperative relation to the inlet opening and discharge opening, and indicating means 00- operating with the pin to designate the feed duct which is in operative position.

In testimony whereof we afiiX our signatures in presence of two witnesses.
